There are many types of piers in a typical Metro Mass Transit System anywhere. Station piers are the most critical piers that are designed for an elevated metro system in any city. A series of these piers constitute an entire metro station. Generally, these are designed as huge expanded double portals the design of which I will expound in some other article. A unique type of station pier is a singular pier with freely hanging cantilevers branching from either sides, support

Grid analysis is the fundamental aspect of bridge engineering as far as understanding any bridge span is concerned Grid analysis or grillage analysis of a span is the virtual modelling and simulation of all forms of conditions and forces upon the bridge span that can occur in its service life. The bending , shear, torsional stresses so developed within the model help us in the preliminary design of bridge girders, diaphragms, cross bracings, and decide other geometrical and
